Just thought some of you guys might be interested in the new Turbosmart Kompact series I saw. It is a direct replacement for your bosch diverter and allows you to vent to the atmosphere and your ecu. It utilizes a 60/40 split and is fully adjustable by hand. Best part is that it will fit perfectly under your valve cover(S4) or in your cramped engine bay(A4). I think it is pretty cool.
